3. Tighten the clamps firmly to the
fixture’s base and to the support.
4. Run the safety cable through the loop
on the fixture’s base, and around the
truss.
Linking DL.2 Fixtures
DL.2 fixtures can be linked with other fixtures on a standard DMX512 link using XLR cabling and
then controlled by a DMX desk. The number of fixtures on a link will be determined by the
combined number of channels required by all the fixtures. The DMX channel range of a DL.2
fixture is determined by the protocol mode you choose.
• Standard Protocol = 170 channels
• Dual Protocol = 132 channels
• Single Protocol = 94 channels
Use data-grade cable and 5-pin XLR cable connectors. Data-grade cable is designed to carry a
high-quality signal with less susceptibility to electromagnetic interference and less degradation
over long distances. For cable and connector specification, see Cable and Connector
Specifications on page 225.
Test each cable with a voltage/ohm meter (VOM) to verify correct polarity and to make sure that
the negative and positive pins are not grounded or shorted to the shield or to each other.
Setting up a Standard DMX Link
To link one or more fixtures to a DMX controller:
1. Connect the male XLR connector of a DMX Data cable to the controller’s DMX Data Out
connector.
2. Connect the Data cable’s female XLR connector to the Data In connector of the first (or
next) fixture on the DMX link.
3. Continue linking the remaining fixtures connecting a cable from the Data Out connector of
each fixture to the Data In connector of the next fixture on the link.
CAUTION!
Do not connect anything to the ground lug on the XLR connectors.
Do not connect or allow contact between the common (cable shield)
and the fixture’s chassis ground. Grounding the common could cause
a ground loop and/or erratic behavior.
